Currently have the 65" ZD9 and thinking of upgrading to the 75" ZH8. Most of the reviews when it was launched criticised the lack of support for certain types of 8K, eg when trying to play 8K files from Youtube using AV1, which apparently is the code which will be used by TV stations, but not supported by the ZH8. Have there been any firm ware upgrades since launch which would solve this problem?
Thanks
